ROPE-GUARD FOR BORING-BIGS.

Specification of Letters Patent. Patented Aug, 21, 191"",

Application filed. April 30, 1917. Serial No. 165,409.

To all whom it may concern Be it known that I, Josnrrr ToMsnNY, a citizen of the United States, residing at VVheeling, in the county of Ohio and State of West Virginia, have invented certain new vide anovel and improved rope guard which serves to maintain the portion of the rope immediately adjacent and above the top of the pipe or casing straight when the drill strikes bottom. I

The invention also has for an object to provide a novel and improved rope guard which may be readily and conveniently rendered inoperative, especially during a bailing operation. a p

The invention consists in the details of construction and in the combination and arrangement of the several parts of my improved rope guard whereby certain lmportant advantages are attainedand the device is rendered simpler, less expensive and otherwise more convenient and advantageous for use, all as will be hereinafter -more fully set forth.

The novel features of the invention will hereinafter be definitely claimed.

In order that my invention may be the better understood, I will now proceed to de scribe the same with reference to the accompanying drawings; wherein- Figure 1 is a view in elevation illustratinga rope guard constructed in accordance with an embodiment of vmy invention in applied position, certain parts being indicated by dotted lines in a second position.

Fig. 2 is a fragmentary view, partly in section and partly in elevation, illustrating certain features of the invention as herein disclosed; and

Fig. 3 is a sectional view taken substantiallyon the line3 3 of Fig. 1 and looking in the direction of the arrow.

As disclosed in the accompanying drawings; C denotes the upper endportion of a pipe or casing such as is generally em ployed in a well boring operation, and the upper orouter extremity of said pipe has affixed thereto a surrounding collar or sleeve 1. I s s A denotes an anchoring member comprising two hingedly connected sections 2, adapted to straddle or embrace the pipe creasing C below and preferably immediately adjacent the collar or sleeve 1. The free ends of the sections 2 have coacting therewith a clamping means 3, whereby the anchoring member A is effectively held in applied position upon the pipe or casing O, yet capable of ready removal therefrom when required. I V p I Each of the sections 2 midway its length is provided with the outstanding spaced wings 4 arranged transversely of the section 2, and between which is pivotally engaged as at 5, an upstanding arm 6 of predetermined length. The upper or free end portion of the arm 6 is provided'with inwardly directed spaced wings 7, having positioned therebetween and rotatably support- 7 passes therebetween. The rope R is adapted to coact in a conventional manner with a drill (not shown), and it will be at once self-evident that the rope It below the rollers 8 will be maintained straight, which is of particular import when the drill strikes bottom, as the rope is thereby prevented from slacking as indicated by dotted lines ata. The slacking or buckling of the rope results in the rope contacting with and being drawn over the upper or outer edge of the pipe or casing C and thereby becoming materially worn, whereas it will be at once perceived that with the use of my improved gear this material disadvantage is avoided and the life of the rope It materially prolonged.

breaded through each of the arms 6 at a predetermined spaced relation relative to the pivot 5 thereof is a screw 9, which serves as an endwise adjustable stop member adapted to contact with the upper or outer end portion of the pipe or casing C, or more particularly the collar or sleeve 1, so that the limit of the inward swinging movement of the arm 6 may be regulated in accord ance with the requirements or necessities of practice.

Each of the arms 6 at its pivoted end is provided with an outwardly inclined tail 10, having its free extremity angular in cross section, with one face oppositely beveled as indicated at 11, and with which co acts the conical end 12 of a screw 14 or the like, disposed through and carried by an end portion of a flat spring 15, held at a point intermediate its length to the outer face of one of the wings 4., by a'pivot member 5, herein disclosed as a headed bolt having coacting therewith a clamping or retaining nut 16. The coaction between the screw 14 and the opposite bevels 11 of the tail 1O serve to maintain the arm Bat the limit of its inward movement, or at the limit of its outward movement as indicated by dotted lines in Fig. 1. The outer position or adjustment of the arm 6 is desirable during a bailing operation.

Each of the springs 15 is held against swinging movement about the pivot member 5 by the finger or screw 17 disposed through the end portion of the spring remote from the screw 14., and which seats within a recess 18 formed in the upper edge of the adjacent wing 4:.

From the foregoing description, it is thought to be obvious that a rope guard constructed in accordance with my invention is of an extremely simple and comparatively inexpensive nature and is particularly well adapted for use by reason of the convenience and facility with which it may be assembled, and it will also be obvious that my invention is susceptible of some change and modification without material departure from the principles and. spirit thereof and for this reason I do not wish to be understood as limiting myself to the precise arrangement and formation of the several parts herein shown in carrying out my invention in practice, except as hereinafter claimed.

I claim:

1. A rope guard comprising a member adapted to be afiixed to a pipe or casing, arms pivotally engaged with said member, the outer portions of said arms being adapted for engaging with the rope, and means for holding the arms at the limits of their movements in opposite directions.

2. A rope guard comprising a member adapted to be affixed to a pipe or casing, arms pivotally engaged with said member, the outer portions of said arms being adapted for engaging with the r0pe, means for holding the arms at the limits of their movements in opposite directions, and adjustable means carried by the arms for limiting the movement thereof in one direction.

3. A rope guard comprising a member adapted to be aflixed to a pipe or casing, arms pivotally engaged with said member, the outer portions of said arms being adapted for engaging with the rope, means for holding the arms at the limits of their movements in opposite directions, and adjustable means carried by the arms for limiting the movement thereof toward the casing.

4:. A rope guard comprising a member adapted to be affixed to a pipe or casing,

arms pivotally engaged with said member, the outer portions of said arms being adapted for engaging with the rope, means for holding the arms at the limits of their movements in opposite directions, each of said arms being provided with a tail, and means coacting with the tail for locking the arm at the limit of its movement in either direction.

5. A rope guard comprising a member adapted to be aflixed to a pipe or casing, arms pivotally engaged with said member, the outer portions of said arms being adapted for engaging with the rope, means for holding the arms at the limits of their movements in opposite directions, each of said arms being provided with a tail, and a yieldingly supported member coacting with the tail for locking the member at the limit of its movement in either direction.

6. A rope guard comprising a member adapted to be aflixed to a pipe or casing, arms pivotally engaged with said member, the outer portions of said arms being adapted for engaging with the rope, and means for locking the arms at their limit of movement in one direction.

7. A rope guard comprising an anchoring member, opposed arms pivotally engaged therewith, means for locking the arms when at the limit of their movement one toward the other, and pulleys carried by the outer end portions of the arms between which the rope is adapted to pass.

8. A rope guard comprising an anchoring member, arms pivotally engaged therewith, the outer portions of said arms being adapted for engaging with the rope, and means for locking the arms at their limit of movement in one direction.

In testimony whereof I hereunto aflix my signature in the presence of two witnesses.
